Eldrazi Engine

When Eldrazi Engine is cast or attacks, exile two
target cards from graveyards or the battlefield.
You may cast exiled cards, when you do you lose
life equal to the card's converted mana cost and
you may spend mana as though it were mana of
any color to cast the spell. If a card cast this way
would be put into a graveyard, exile it instead.
Creatures cast this way are Eldrazi Zombie
Horrors in addition to their other types.
